        const context = new TurnContext(adapter, req);
        context.sendActivity('Hello, I am your chatbot!');
    }
});
const restify = require('restify');
const server = restify.createServer();
server.post('/api/messages', (req, res) => {
    adapter.processActivity(req, res, async (context) => {
        // Your bot's logic goes here
    });
});
server.listen(3978, () => {
